gosh he's so handsome! what a color!!
I'd be interested to hear how well linnies and budgies get along, please!
Actually, my first bird was going to be a budgie, but I decided to get two, so one would not be lonely when I was away from home. Then while I was waiting for the budgies to fledge so I could bring them home, I found a double-wide flight cage on craigslist & figured they'd like a big home. The catch was there were 2 Linnies already occupying the cage when I went to pick it up. [Four Linnies, actually, but the owner removed 2 & put the other 2 in a box & handed it to me].
Too late to make a long story short, but I had 2 budgies in one half of the [dividable] double flight cage & 2 linnies in the other half for 4 years.
While mine really did not get along well - The Evil Dragon Queen [who passed just this week] bedeviled the Linnies, guarded the dividing wall and tried to grab the Linnies' tails or beaks at every opportunity - I think that was possibly a matter of her personality. The sweet remaining budgie, Little Bird Blue, seems to get along with them just fine, although they really don't interact much.
It may be different with a single budgie and a single Linnie, although budgies are bigger and more assertive than linnies.
Best of luck - you have a very cute little guy. They will be company for each other, whether they become best buddies or not.
